Question type: Maintenance & Repair
Sometimes the car sounds like it has a dead battery and cranks over slow and starts. Other times it is fine. If I start it with the battery charger hooked up it starts right up. Battery is 5 months old

Try the alternater it could be draining ur battery.
Check the voltage with the engine running. It should be more than 14 volts. Check the voltage after sitting all night - it should be around 12-12.5 volts. If the morning voltage is lower, either the alternator is not charging fully or there is something slowly draining the battery. --- You do not want anything draining that new battery. A battery life is about 300 full cycles. Every night that your battery is drained, it uses some of that life.
